why does it need the lock the whole time? Is someone getting known stale data (when you could tell them to wait) always OK, but overwriting someone else's change never is?

In a threaded environment, it shouldn't really be a problem as long as the view of the data is consistent. It's no different from what would have happened if the reading thread had got there just a moment sooner, before the writer got hold of it.

If that's a problem, there should have been some higher-level synchronisation going on before getting to that point.
